 Health Guide Drug Guide Images EmpyemaDefinitionEmpyema is a collection of pus in the space between the lung and the inside of the chest wall (pleural space). CausesEmpyema is caused by an infection that spreads from the lung. It leads to a buildup of pus in the pleural space. There can be a pint or more of infected fluid. This fluid puts pressure on the lungs. Risk factors include:
In rare cases, empyema can occur when a needle is inserted through the chest wall to draw off fluid in the pleural space (thoracentesis) Symptoms
Exams and TestsThe health care provider may note decreased breath sounds or a friction rub when listening to the chest with a stethoscope (auscultation). Tests may include the following:
TreatmentThe goal of treatment is to cure the infection and remove the collection of pus from the lung. Antibiotics are prescribed to control the infection. The health care provider will place a chest tube to completely drain the pus. A surgeon may need to perform a procedure to peel away the lining of the lung (decortication) if the lung does not expand properly. Outlook (Prognosis)When empyema complicates pneumonia, the risk of permanent lung damage and death goes up. Patients will need long-term treatment with antibiotics and drainage. However, most people fully recover from empyema. Possible Complications
When to Contact a Medical ProfessionalCall your health care provider if you develop symptoms of empyema. PreventionPrompt and effective treatment of lung infections may prevent some cases of empyema.
